CALIBRATION SPRING ADJUSTER FOR A SEAT BELT SYSTEM
First Claim
1. A calibration spring tension adjuster for a seat belt tension sensor comprising a fixed part, a movable part, a holder attached to the fixed part, and a calibration spring held between the holder and the movable part, wherein the fixed part and the movable part are adjacent to each other and comprise mutually facing stepped helical faces arranged so that the movable part can be rotated relative to the fixed part causing the respective stepped helical faces to slide over each other to change a gap between the stepped helical faces and tension the calibration spring.

Abstract
A calibration spring tension adjuster for a seat belt tension sensor has a calibration spring, and a holder. The fixed part and the movable part are adjacent to each other and comprise mutually facing stepped helical faces arranged so that the movable part can be rotated relative to the fixed part causing the steps to slide over each other causing a gap between the stepped faces to increase and compressing the spring. The steps can be arranged so that movement of the movable part in one direction is resisted. The holder is arranged to attach to the fixed part and the spring is held between an abutment face of the holder and a non-stepped face of the movable part.
